Changelog for hslua-classes-2.1.0

Changelog

hslua-classes uses PVP Versioning.

Released 29-01-2022.

Updated to hslua-core 2.1 and hslua-marshalling 2.1.
The Peekable class has been remodeled:
- Peekable now contains safepeek, which is a Peeker function for the type.
- peek is no longer part of Peekable, but a normal function defined as forcePeek . safepeek.
HsLua.Class no longer exports peekList and peekKeyValuePairs. Use the functions from HsLua.Marshalling instead.
The Exposable class is changed to use the Peek monad instead of LuaE, thereby unifying the way errors are reported in HsLua.
PeekError has been removed; it is now sufficient for exception types used with Peekable, Exposable, and Invokable to be instances of LuaError.
The Invokable type class now has a single parameter. This removes the need for the AllowAmbiguousTypes extension and makes using invoke much more convenient, as the proper error type can now be inferred automatically.
Added function pushAsHaskellFunction to make it even easier to use Haskell functions in Lua.

Released 2021-10-21.

Initially created. Contains modules previously found in the Foreign.Lua.Types hierarchy from hslua-1.3.
